Be it known that I GEORGE F. LYNN, a citizen of the Uziited tates, andresidept of Detroit, Wayne county, State of Mlehigen,

have invented certain new end useful im- I prosements in Methods ofMakmg Hydro- 3 1. R csi'oe-iiiotors, o: whip 2 4 SE ESL-282241163.

j ecket 20 at the lower shown in Figzi. 2 and 3 is now bent over ordownwardly as shown in Figs. 4 and 5. If the flange is to becircularthis shape may be obtained by the original machinin operation but withthe irregular shape 0% flange shown in Fig. 5, used to permit twocylinders to be brought closely together, theflange is preferably formedradially as shown in Fi 2 and then bent over by the use of suitab etools.

Fig. 6 illustrates in perspective a two part tool which may be used forbending over the flange. This tool comprises blocks 31 and 32 pivotallyconnected together by a link 33 and detachably connected at their otherends by a bolt 34, The upper portions of the blocks form an anvil 35 ofthe desired shape of the down-turned flange and these blocks are clampedabout the cylinder directly beneath the flange 25 as shown in Fig. 7. InF ig.'8 the. flange has been ham mered or otherwise bent downover theanvil 35 and the bent portion 36 of the flange forms a skirt to whichthe sheet. metal water 'acket above referred tofmay be secured.

he tool 31 may be 'rea'dil re n-eyed from the cylinder after:th'e ben'ng'nover opera- .tion. a

In Fig. 9 the-c'ylinder-Bis shown inverted and a water jacket 37 isshown surrounding the cylinder and the flange 25. The water jacket is incontact with the bent over part 36 of the flange 25 and its extreme end38 is welded together.

in juxtaposition to the end of the skirt 36. These two piecesof metalare of substantially the same thickness and they are advantageouslypositioned for applying awelding heat without too greatly heating thebody of the cylinder. In Fi 10 the welding has been applied at 39 to t eends of the jacket and skirt and those two parts have been In Fig. 11,two' cylinders B are shown and they are arranged so closely togetherthat the straight part 40 of the skirt .36 of one cylinder-is in contactwith the strai ht part of the shirt of the adjacent cylin er. Thesestraight parts of the skirts may be heated and thereby weldedto ther anda single jacket 37' is then lacefiround both of the cylinders and wel edto the curved parts of t e skirts in the manner illustrated'm Figs. 9and 10. The cylinders may also be welded together at their bases wheretheir flanges come together as shown at 41 in Fig. 11.- But a singleform of the invention is shown and described herein. However it will beunderstood that other forms and =1'nodifications may be made withoutdeparting from the spirit .or sco of the claims.

Having thus escribediiiyf inventiomwhat' I claim and desire b'y 'LettersPatent is:

I 1. 'A method ofinaking cylinder blockf sharedv l.

a water jacketarou'nd the two cylinders incontact with the parts of theskirts that are not so welded together, and welding the ends of saidjackets to the ends of said skirts.

- 3. method of welding a sheet metal jacket to a cylinder consisting informing the c linder with an external radial flange, bending the outerpart of the flange over, placing the jacket over the flange with its endin juxtaposition to the bent over part of the flange, and heating saidjacket end and flange to cause them to flow together.

4. A method of welding a sheet metal jacket to a c linder consisting informing the cylinder wit an external radial flange, bending the outerpart of the flange over parallel with the cylinder wall, placing thejacket over the flange with its end in juxtaposition to the bent overpart of the flange, and heating said jacket and and flange to cause themto flow together.

5. A method of welding a sheet metal jacket to a steel cylinderconsisting in forming the-cylinder with an integral external radialflange, bendin the outer part of the flange over, placing t e jacketover the flange so that it surrounds the cylinder and flange and withits end coinciding with the end of the flange, and heating said ends tocause I of welding a sheet metal A ing the cylinder with an integralsteel flange having a down-turned outer part, lacin I the jacketaroundthe cylinder with its en in juxtaposition to the flange, andheating the jacket end and the flange to cause them i to flow together.

7 A method of making a jacketed motor a radial cylinder consisting informin ndmgl the flange on the cylinder proper,

and flangeito cause them to flow. together.

' 1.8. A method'of making-a jacketed motor c linder consisting informing an irregularly s aped radial flange on the cylinder proper,bending the outer part of said flange over-a lac ng metal parts ofsubstantially the thickness of said bent ever part in contact with saidbent over part of the flange, and heating the bent over part,

of said ange and the metal in contact therewith to cause them to flow toether.

9. A method of makin a 3acketed motor cylinder consisting in orming anotched irregular radial flange on the cylinder proper, bending theouter part of sai over a she d anvil, lacing metal parts of 10substantia y the thic cm of said bent ever part in contact with saidbent overpart of the flan e, and heating the bent over part of saidange'and the metal in contact therewith to cause them to flow together.
